Danish Signaling, Speed Boards

General use and appearance

The subject speed boards (danish: standsignaler)
covers circular, triangular and square boards used for indication of
speed restrictions and track barring. Such boards are erected next to
the track, or in the middle of the track (barring only).

Every line has a prescribed speed limit which is not
indicated further. Only restrictions - i.e. speed limits lower than the
prescribed speed - are indicated by speed boards. Numbers on speed
boards are to be interpreted as km/h.
